The present disclosure relates to high-temperature proton exchange membrane fuel cells (HT-PEMFCs) having phosphoric acid as a proton conductor comprising an anode, a cathode, and a proton exchange membrane (PEM) disposed between the anode and the cathode; and at least one catalyst layer disposed on the proton exchange membrane (PEM). The at least one catalyst layer comprises multi-metallic Cu—Pt—Au alloy catalyst nanoparticles comprising from about 5 to about 30 at % gold (Au), from about 5 to about 50 at % copper (Cu), and from about 30 to about 90 at % platinum (Pt).
A proton exchange membrane fuel cell (PEMFC) comprising:
A membrane electrode assembly (MEA) for a high-temperature proton exchange membrane fuel cell comprising phosphoric acid or phosphonated ionomers as a proton conductor or a catalyst binder, said MEA comprising:
